HORSESHOE-CALK.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application led January 1'7, 1905. Serial No. 241,516.

To L7/Z whom, it may concern.-

Be it known that I, JESSE S. MAeooN, Jr., a citizen of the UnitedStates, residing at Charlton, in the county of Worcester and State ofMassachusetts, have invented a new and useful Horseshoe-Galli, of whichthe following is a specification.

This invention relates to that class of horseshoe-calks which areintended to be replaced as frequently as worn out.

The special object of this invention is to provide a horseshoe-calliwith a removable shell which is held in place by the resilience ofspring metal.

A further object of this invention is to provide ahorseshoe-calk withacushion for taking up jar.

To these ends this invention consists of a horseshoe-calk and itsremovable shell as articles of manufacture and of the combinationstherewith, as hereinafter described, and more particularly pointed outin the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a perspective view of ahorseshoe equipped with horseshoe-calks according to this invention.Fig. 2 is a detail view of one of the calls, the shell being shown insection. Fig. 3 is a sectional view of the removable shell. Fig. i isabottom View thereof, and Fig. 5 is a side view of the calk with itsshell in place.

In that class of horseshoe-calks to which this invention relates it hasalready been proposed to use detachable calks which are threaded intothe horseshoe by the use of threaded studs for this purpose, and it isnow possible to renew the calks of a set of shoes comparatively quicklyand without danger of injuring the horses hoofs.

The special object of my present invention is to further improve thisclass of horseshoecalks by the use of replaceable shells which arepreferably slotted or provided with gripping-fingers of sufficientresilience to hold the shells in place when they are forced over theheads of the studs or projections mounted in the horseshoe.

Referring to the accompanying drawings, the shoe A may be of theordinary or approved construction. Y In the shoe A are four calks. Eachof these calks, as illustrated more clearly in Figs. 2to 5, inclusive,consists of a threaded stud 10, having a collar 11, with a substantialball shaped head 12. A replaceable shell which I employ for renewing orrefitting a horseshoe-calli is tted up with a shell of substantiallyacorn shape-that is to say, each of these shells is pointed at one endand is provided at its other end with an inwardly-bent resilientgripping iiange or fingers 14.

In the particular form of shell illustrated in the drawings the closedend of the shell is provided with a sharp point. This particular shapeof shell is used when it is desired to keep the horseshoe -calk sharpduring slippery or icy weather, for summer use, and on bare ground. Theclosed end of each shell instead of being pointed may be somewhatflattened to provide a larger wearingsurface. By means of thisconstruction when a shell has been `hammered or forced over the head ofa stud it will grip itself firmly in place. When the calk becomes worn,the old shell can be taken oli" by means of pipe-tongs or other tools,and a new shell can then be forced into place. By this means it ispossible to reequip a set of horseshoes very quickly and eficiently.

In some cases, in order to cushion the horseshoe-calks, I interpose asmall piece of rubber, as 13, between the head of the stud and theshell.

I am aware that changes may be made in the shape and proportions of theparts of a horseshoe-calk constructed according to my invention Withoutdeparting from the scope thereof and as expressed in the claims. I donot wish, therefore, to be limited to the construction I have hereinshown and described; but

What I do claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. As an article of manufacture, a replaceable cover for thehorseshoe-calli consisting of a metal shell closed at one end and havinga crimped-in holding-flange at its other end.

2. As an article of manufacture, a horseshoe-calk consisting ofathreaded stud having a substantial ball-shaped head and a replaceablecover consisting of a substantial acornshaped metal shell having a pointat one end and resilient gripping-fingers at its other end.

3. As an article of manufacture, a cushioned IOO horseshoe-@211kconsisting of a threaded stud In testimony whereoflhavehereunto set myhaving a substantial ball-shaped head, a rehand in the presence of twosubscribing witplaeeable cover consisting of e substantial nesses.
